Race identification of others and oneself is a product of being a bit dumb, frankly. "Dumb" in the sense of emotional immaturity.

Politicians, corporations, and anyone trying to sell or push anything, will use race to divide up people into factions (or emphasize this "dumb" tendency). The style of politics that use race is a pretense designed to represent virtue.

Obama achieved zero for positive race relations although his zero result was his personal achievement.

There will always be uneasy universal race relations because too many individual persons identify themselves as a particular race or particular mixes of race.

It is all just typical, everyday, common garden variety, narcissism.

The modern left got rid of the melting pot, by persuading people to assume their native or newly defined cultural identities. This creates social dysfunction, which makes more and more people dependent on big Government, to make it fair, for everyone, via a regulated slow pace; quota system. The better solution was assimilation into that which works the best. — wellwisher

If they stay alive they are right in their own rights. Why should one burden oneself with problems when the alternative is causing someone else problems?
The organization of groups seems to be an appropriate strategy when trying to make things someone else's problem. We see this everyday in changing legislatures, court rules and so on.

I have something to note about Peterson's lecture:

If a state, the modern institutionalization of souvereignity would declare itself Marxist you already know that the principle to side with the oppressed was left behind. Note that this never happened. Socialism is the first step of degeneration of capitalism when it get's realized that the rule of money alone is leading to a disaster and the freedom of the capital gets restricted. Communism is it's complete collapse when the starving majority of people starts raiding markets having all the needed goods they cannot afford and/or the violent takeover of the means of their production.
Recently I saw a documentary on TV about a project of the EU to support economy in Africa. Seemingly humanitarian the declared intent was to settle up industry to strengthen economy and this promote welfare in poor regions. What they got was a huge, super-modern farm complex that can operate with an absolute minimum of human work. What this did for the people is that for a few weeks in a year some helpers get hired with absolutely no chance of a longer employment. The majority of the time all that is needed is a few overseers that keep the machinery intact - which cannot be done by locals as these are generally unqualified to do so. Needless to say that the food produced is not sold locally (where should these people have the money from?) but on the world market.
The USSR did support some seemingly "backward" forms of existence like sealers in Siberia. Now these are dying out, forced into civilization where they and their families typically have a hard stand if you would call the life of a sealer in Siberia "easy".
The death toll is not just composed of murder.
